Show us the code you have written that you think should display the picture and whatever is shown on screen where the image should be displayed. First have a look at the html being generated (View > Page Source or similar in your browser) and make sure that the html being generated is what you expect. I would expect you to be using image_tag to show the image.> and i try to use the plug in paperclip.. > and when i install it on the current project,, I cannot run my server > in Terminal,,Is this a separate question? If so I would advise just having one question in a post, otherwise the answers to the two questions will get mixed up. Again though it is no good just saying you cannot run the server, otherwise the only reply you will get is that you are doing something wrong. Tell us the error message when you run the server.

Here''s how I display images with paperclip:
<% if items.picture.url(:medium) =~ /missing.png/ %>
<%= link_to image_tag( items.picture.url,:size =>
''300x300'', :border=> 0), items.picture.url, :target =>
''_blank'' %>
<% else %>
<%= link_to image_tag( items.picture.url(:medium), :border=> 0),
items.picture.url, :target => ''_blank'' %>
<% end %>
Notice the image tag - items.picture.url not the base object.
Hope this helps.
